In this activity, students will explore arithmetic sequences and series.

• Students will explore sine, cosine, and tangent with respect to the ratios of the sides of right triangles.
• Students will use the TI-Nspire CX II to discover the relationship of these three trig functions.
• Students will solve any right triangle given an angle and the lengths of the opposite side, adjacent side or the hypotenuse.
• Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments.

Students will explore sine, cosine, and tangent with respect to the ratios of the sides of right triangles.

*Note: This activity includes optional IB support, including IB Questions download for students who are preparing for the IB Exam.
